Scalable synthesis of mesoporous titania microspheres via spray-drying method

Mesoporous TiO2 and Fe3O4@mesoporous TiO2−x microspheres have been synthesized by coupling the template-directed-sol-gel-chemistry with the low-cost and environmentally benign spray-drying technique. As-made microspheres were observed in a size range of 500 nm to 5 μm, specific surface areas from 150 to 162 m2 g−1 and mean pore sizes of 4-6 nm. Moreover, Fe3O4@mesoporous TiO2−x microspheres exhibited remarkable selective phosphopeptide enrichment activity.128
